Advances In S-Band Radar Technology: Reducing Overall System Cost Through Higher Levels Of Integration
By Brian D. Battaglia, Jeff Burger, and John Titizian, Integra Technologies, Inc.
The S-band has long been an application space servicing both commercial and military radars. Many radar systems in the past required very high peak power levels with low to medium pulse widths that were best served by silicon bipolar technology. In the last few years, the trend in radar systems requires longer pulse widths and some measure of linearity. The designers at Integra Technologies have developed a product that offers a complete 50-ohm RF power solution in a single package. Miniaturized power amplifiers utilizing LDMOS (MPALs) are matched to 50 ohms at the package leads and only need a bias circuit to complete the solution.
